This is a list of jazz and popular music terms that are likely to be encountered in printed popular music songbooks, fake books and vocal scores, big band scores, jazz, and rock concert reviews, and album liner notes. This glossary includes terms for musical instruments, playing or singing techniques, amplifiers, effects units, sound reinforcement equipment, and recording gear and techniques which are widely used in jazz and popular music. Most of the terms are in English, but in some cases, terms from other languages are encountered (e.g. to do an "encore", which is a French term).

4-track (or "four-track")

A simple portable recording and mixing device widely used in the 1970s and 1980s which used compact cassettes.

5-string (or five-string)

An electric bass with five strings, which often means the addition of a low "B" string.'

6-string (or six-string)

An electric bass with six strings, which often means the addition of a low "B" string and a high "C" string. (Note: in uncommon cases basses with even more strings are used. 6-string bass may as well refer to bass guitar tuned as a typical guitar with an octave down, such as Fender Bass VI). It is also a common slang of guitar.

7-string (or seven-string)

An electric guitar with seven strings, which often means the addition of a low "B" string. Seven-string guitars are associated with jazz, fusion, and metal styles.

8-string (or eight-string)

A tape format popular in the 1970s.

8x10"

...with eight ten-inch loudspeakers. Used in electric guitar and bass cabinets. It is sometimes called a "stack", and, in the case of a bass cabinet, a "bass stack".

Sound equipment in which the signal containing the voice, electric guitar signal, etc. is electrical, rather than converted into digital "1's" and "0's" (binary system). Whether analog or digital recording and effects are "better" is a subject for debate. Proponents of analog effects and mixing boards often argue that analog gear has a "warmer" or more "natural" tone.

Like a harp (i.e. the notes of the chords are to be played quickly one after another (usually ascending) instead of simultaneously). Arpeggios are frequently used as an accompaniment. See also broken chord in this list.

An avant-garde genre of rock that is related to progressive rock (Genesis; Rush; Gentle Giant); both genres tend to use unusual instruments, meters, and timbres, and both aim towards more complex, experimental compositions and novel sonic textures.

as is

A jazz term which instructs the performer to play the noted pitches as they are printed. Parts for jazz musicians in big bands often consist of lengthy sections of empty bars labelled with the changing time signatures and chord changes. Rhythm section members improvise an accompaniment (see Comp), and lead instruments improvise solos. In sections where the jazz arranger wants the performers to read notated pitches rather than improvise, they indicate this with the notation "as is".

axe

A slang term which refers to an electric guitar, or, by extension, to any instrument (e.g. a bandleader may tell a saxophone player to "get your axe").

The lowest of the standard four voice ranges (bass, tenor, alto, soprano); the lowest melodic line in a musical composition, often thought of as defining and supporting the harmony; in a jazz or popular music context, the term usually refers to the double bass or the electric bass.

Jazz term referring either to establishing a pitch, sliding down half a step and returning to the original pitch or sliding up half a step from the original note. With the electric guitar, bending is widely used in blues, blues-rock, and rock and, to a somewhat different fashion, in jazz.

bin or bass bin

A subwoofer cabinet that reproduces very low-frequency sounds, usually with some type of horn or transmission line system to enhance the bass response; typically used for the main, Front of House speaker system, but in rare cases, may also be used as part of a bass player's bass amplifier set-up. The term "bin" was more common in the 1980s; in the 1990s and 2000s, the term "subwoofer" or "sub" is much more widely used.

A slang term for fermata, which instructs the performer to hold a note or chord as long as they wish

bleeding, bleed, or bleed-through

A slang term which refers to the ambient sounds that a microphone aimed at instrument A picks up from other instruments or singers in the same room. In some cases, "bleeding" is considered undesirable, if unwanted sounds from other instruments are picked up by a microphone. For example, if a guitar player plays an amazing solo during a recording, it may end up being unusable if mistakes by the drummer—20 feet away—are bleeding through into the mic in front of the guitar amp. To prevent "bleeding", studios use isolation booths and cloth-covered room dividers. In some cases, "bleed-through" is desirable, because it makes the recording sound fuller or more "live".

block chords

A style of piano playing, developed by Milt Buckner and George Shearing, with both hands 'locked' together, playing chords in parallel with the melody, usually in fairly close position. It is a technical procedure requiring much practice, and can sound dated if the harmonies are not advanced enough. Also called locked hands.

blow

A jazz term instructing a performer to improvise a solo over the chord progression of a jazz tune; may also be written "blowing section" or, in free jazz, "open blowing"

Yamaha 2403 audio mixing console in a 'live' mixing application. Each column of knobs controls the volume, tone, and other elements for a single channel (e.g. a microphone being used by a singer).

blues

In a jazz context, when "blues" or "solo on blues" appears at the start of a solo section, it is an abbreviation for "blues progression"; it instructs the performer to improvise solos over a 12-bar blues progression based on I, IV, and V7 chords.

board

A shortened form of "mixing board", which refers to the audio mixing board used by live sound engineers and studio engineers to control the volume and tone of different instruments and voices, blend them in the desired proportions, add external effects (e.g. reverb), and route the final signal (or an intermediate signal) to desired locations (e.g. to a recording device; to Front of House speakers; to monitor speakers, etc.). The term "board" may also be used as a shortened form of "fingerboard".

break

Transitional passage in which a soloist plays unaccompanied.

bridge

Transitional passage connecting sections of a composition. A "bridge" is sometimes referred to as "the middle eight" and is often employed to introduce variation to songs or chord progressions which lack enough variety to keep the listener engaged. Secondly; a "bridge" refers to the part of a stringed instrument that holds the strings in place and transmits their vibrations to the resonant body of the instrument as well as being the terminus of a string's vibrational length. The other vibrational terminus is often referred to as the "nut" which is often made from bone, hard plastic or bronze and located at the end of the fingerboard near the "head" and tuning keys.

broken chord

A chord in which the notes are not all played at once, but rather one after the other (i.e. an arpeggio).

A speaker cabinet, which is a wooden (or sometimes plastic) enclosure for a loudspeaker and, in some cases a horn or tweeter. Speaker cabinets are used to amplify instruments and vocals.

cadence

The point at which a melodic phrase "comes to rest" or resolves. A cadence often occurs on the "tonic" note (supported by the tonic chord—the "home chord" of the key). A cadence can also occur on other notes over the "tonic" chord, or over another chord such as the "dominant chord" (the chord built on the fifth scale degree). One of the features of Classical music is that cadences are often elided; that is, instead of coming to rest at the cadence, a new musical line commences at exactly the same time of the cadence. This helps to create a forward momentum in the music

call and response

A way of writing a song in which after a singer sings a line, other singers (e.g. backup singers or band members) respond with a line that completes the thought. Call and response singing was originally part of African-American work songs, and it subsequently became an important part of the blues.

capo

A clip-on metal or plastic device with a rubber-padded bar which holds down all six strings of the guitar in a fret position selected by the performer. It is attached with an elastic or spring-loaded mechanism. It allows a guitar player to have the open strings start at a higher pitch, thus facilitating the transposition of songs and the use of the "ringing", rich sound of open chords in unusual keys.

changes

A jazz term which is an abbreviation for "chord changes", which is the harmonic progression (or "chord progression") upon which a melody is based.

channel

In the context of a mixing board, a channel is one of the input sections into which a microphone or output from an instrument amplifier or instrument (e.g. an electronic keyboard) is plugged so that its volume and tone can be altered and so that it can be blended with other instruments and voices; in the context of an electric guitar amplifier or a bass amplifier, the term "channel" is used to refer to amplifiers which have two or more separate preamplifier, equalization, and effect settings ("channels") which a performer can switch between in a performance via a footswitch.

chicken pickin'

A colloquial expression describing a particular touch and style of electric guitar playing usually using a "clean" amp tone and employing a percussive or sharp attack, which when combined with alternating short and longer notes effectively, is meant to emulate the clucking and squawking of a chicken, thereby providing an unmistakable rural element. Sometimes played without a guitar pick, it is best voiced on the Fender Telecaster guitar or similar "thinner" instruments with single coil pickups. It has become a standard color and flavor within traditional American "country" music particularly from the 1960's and 70's. It is virtually never used outside of 'hard' country music.

chops

A slang term which refers to a player's strong technique or endurance ("That alto sax player has great chops; she can play for hours.")

A group of three or more notes that, when played simultaneously, can form a harmonic structure that can support a melody or a solo line. The simplest chords are triads, which are made of the first note of a scale and then alternate notes. For example, in the scale of C Major (C,D,E,F,G,A B,C), the triad would be C,E,G. Seventh chords use four notes: they consist of a triad with an added interval. For example, in the scale of G Dominant (G,A,B,C,D,E,F,G), the four-note seventh chord would be G,B,D,F. There are also more complicated chords which add additional intervals (see ninth chord, "alt dom"). A chord can also be played one note at a time (see "arpeggio" and "broken chord").

chorus

1. The refrain of a song which is repeated a number of times, in alternation with verses and other sections (e.g. a guitar solo). In contrast to the verses of a song, the chorus tends to be simpler and more memorable, and it often uses more repetition of lyrics (e.g. "She loves you yeah, yeah, yeah...").

(Note to sheet music fans; in the early 20th century into the 1940's the term "chorus" was often used for what is currently defined as the "intro", sung only once at the top. As an example from later in 1966; the three measure introduction to the P. McCartney song "Here, There and Everywhere"... "to lead a better life" etc., would have been the 'chorus' to many or most publishers.)

2. The term "chorus" may also be a synonym for "choir"—a group of singers; (Note that in the early 20th century into the 1940's the term "chorus" was often used for what in the 21st century is defined as the "intro", sung only once at the top.
As an example from 1966; the three measure introduction to the P. McCartney song "Here, There and Everywhere", i.e., "to lead a better life" etc., would have been the 'chorus' to many or most publishers.)

3.It may refer to a chorus effect—the sound created when a voice or instrumental tone is doubled by other pitches which are not exactly the same, which creates a rich, shimmering sound.

A sequence of all twelve notes in an octave, played in a row (either ascending or descending). Fragments of the chromatic scale are used in many styles of popular music, but more extensive use of chromatic scale tends to occur in jazz, fusion, and the more experimental genres of rock.

clam

A slang term which refers to a mis-played or out of tune note, often by a horn player, but even more often and more regrettably by a too-loud guitar player.

clean

In reference to the sound of an electric guitar, Fender Rhodes electric piano, or other electric or electronic instrument, or to a recording of a singer or instrument or to an entire mix, "clean" means that the sound is undistorted and not muddy. For an electric instrument, the opposite of a "clean" tone is an overdriven, "clipped" (see "clipping"), or "dirty" sound.

clean channel

Many electric guitar amplifiers have two "channels": a clean channel, which is undistorted, and an "overdrive" (or "dirty" channel), in which the signal is heavily preamplified or run through a distortion effect, thus producing a distorted signal. Amps with two channels come with a footswitch which allows the performer to switch between the two channels.

clipping

A synonym for distortion. With vocals, mic'd acoustic instruments, Front of House mixes, and monitor mixes, clipping is almost always deemed to be undesirable, and it is minimized by reducing gain levels, using compression devices, adding "pads" (attenuation circuits), etc. With electric guitars, electric basses, Hammond organs, electric piano, and other electric instruments, performers often purposefully add clipping to the signal by boosting the gain or using an overdrive pedal.

The Roland VK-7 is referred to as a "clonewheel organ", because it recreates the sound of vintage tonewheel organs like the Hammond organ.

An electronic or digital instrument which recreates or imitates the sound of a tonewheel-based Hammond organ, typically in an instrument that is much lighter and smaller than an actual Hammond organ (e.g. the Roland VK-7 or the Korg CX-3).

A tail (i.e. a closing section appended to a piece of music). Also called a "tag" or "outro".

colosseum ending

An expression originating from electric guitar-based rock bands describing a dramatic and dynamic performance effect, specifically, a loud ending used by rock bands when playing in large outdoor venues or similar large shows. Occurring on or after the last chord of a song, typically it's 4-10+ seconds of loud sustained chord(s) often with many drum fills with improvisation or activity from others to create a steady, rumbling or churning effect. Similar dynamic finales are found throughout symphonic music intended to create excitement and rouse the audience to massive applause and ovation.

combo

An abbreviation for "combination", which is used in two senses in jazz and pop music. "Combo" can be the equivalent of "group" or "ensemble" (e.g. "a jazz combo"). As well, "combo" refers to a "combination amplifier", so named because it includes an amplifier and a speaker in a single cabinet.

comp

A jazz term which instructs a jazz rhythm section performer (usually a chordal instrument such as jazz guitar, jazz piano, Hammond organ, etc.) to play accompaniment chords. In a recording context, the term is an abbreviation for "composite", which refers to recording composite tracks.

comp tickets

An abbreviation for "complimentary tickets", which promoters give out to ensure that a concert will have a good-sized crowd; as well band members and touring staff may be given comp tickets that they can give to friends or family, as a "perk"

compressor

An electronic audio effect which automatically reduces the gain of a signal (vocals, instruments, etc.) to a pre-set threshold, thus preventing unwanted peaks which could cause clipping. A compressor with extreme settings becomes a limiter, which protects speakers and horns from peaks.

A microphone that uses the technique of "variable capacitance" to pick up sound. The diaphragm is on a charged metal plate, and as such, condenser microphones need power to operate. The power comes either from batteries or from a mic preamp or a mixing board. The power that is provided from a preamp or mixing board is called "phantom power".

cover or cover tune

When a band plays a song that has been composed and recorded by another band, this is called a "cover tune"; also used as a verb (e.g. "to cover" a song by a certain band). The term may also refer to a cover charge, the door fee charged to customers for admission to a band's performance at a bar (the cover charge may go entirely to the band or it may be split with the bar, based on the agreement between the band and the establishment).

crossfader

On a DJ mixer, a crossfader is a control that slides on a left-to-right track. It allows a DJ to alternate between two channels, into which an audio input is plugged (e.g. a record player, CD player, iPod, etc.). The left-most position of the slider control gives only Channel A. The right-most position gives only Channel B. The area of the sliding track between these two extremes is a blend of the two Channels. Crossfaders can be used to create smooth transitions between two songs on different sound inputs, or, when moved rapidly at the same time that a record is manipulated on a turntable, they can be used in create rhythmic scratching sounds and effects.

crossover

In a music industry context, a "crossover artist" or "crossover band" is a performer or group from one style that has managed to garner a following amongst fans of a different musical style. For example, some country performers have managed to get "crossover" hits in the pop charts. In an audio engineering context, a crossover is a frequency filter system that divides the frequencies in a signal into low and high or low, mid, and high components. In this way, the different frequencies can be routed to the appropriate speakers.

crunch

Used to describe a specific type of highly distorted, mid-boosted electric guitar tone used in heavy metal and thrash metal music, typically by the rhythm guitarist. When played with palm muting, it creates a characteristic heavy rhythmic sound.

Same as the meter 2/2: two half-note (minim) beats per measure. Notated and executed like common time (4/4), except with the beat lengths doubled. Indicated by three-quarters of a circle with a vertical line through it, which resembles the cent symbol ¢. This comes from a literal cut of the C symbol of common time. Thus, a quarter note in cut time is only half a beat long, and a measure has only two beats. See also alla breve.

An adjective that means non-reverberant, as in the case of a room in a recording studio that has very little natural reverb or ambience (e.g. a "dead room"). To "liven up" the sound of a track recorded in a "dead room", engineers will typically add electronic reverb effects. Alternately, the track could be re-recorded in a room with more reflective surfaces, to add natural reverb.

Decibel (dB)

The unit of measurement of audio level used in recording studios and by live sound engineers. Some cities and performance venues have decibel limits for live performances.

desk

British term for a "mixing board".

DI or DI Box

An electronic device which alters the impedance of electric instrument signals (e.g. electric guitar, electric bass) so that they can be plugged into a mixing board or PA system. The DI box converts a high-impedance, unbalanced signal from an electric guitar into a low-impedance, balanced signal. Many DI boxes have a ground lift switch to remove AC hum from the electrical system.

Digital Signal Processing (DSP)

The use of digital effects to alter the tone, sound, pitch, or other parameters of a signal. Many 2000s-era mixers, guitar amplifiers, and electronic keyboards have on-board DSP effects.

downtuned or detuned

A guitar or bass that is tuned to a lower pitch than the standard tuning, which is (from low to high) EADGBE for guitar and EADG for bass.

dragging

A term used to describe the undesirable act of playing too slow in relation to the existing tempo when no decrease in tempo is called for. The opposite of "rushing". Not to be confused with intentionally or acceptably playing "behind" the beat while keeping the tempo or BPM (Beats per minute) steady.

drive

An abbreviated form of "overdrive", which refers to the distortion that occurs when a tube amplifier is pushed to its limits.

drop

Jazz term referring to a note that slides chromatically downwards to an indefinite pitch .

DSP

See "Digital Signal Processing".

dry

A signal that has no reverb effect, or more generally, a signal that has not been processed with any effects unit. Vocals are almost always recorded "dry", and then the reverb or other effects are added in post-production. Electric guitars and electric keyboards are often, but not always recorded with their effects (distortion, chorus, etc.) already added.

An expression used subjectively (sometimes derisively) to describe audio effects or instrumental parts or tracks which might be considered as non-essential to the core arrangement or composition, but instead add sonic elements such as; "sparkle", "shimmer", "depth" etc., to a recording or mix. Ear candy is often considered acceptable or even desirable within some 'popular' music productions, but is rarely heard within more "roots-based" musics such as blues, bluegrass and other styles relying more strictly on a live musical performance, as opposed styles utilizing complex production values and electronic effects etc.

The Ibanez Tube Screamer overdrive pedal, an effects unit with a footswitch to turn the effect on and off

An electronic device which alters or conditions the sound qualities in an electronic signal from a microphone, musical instrument, or recording. Effects units can be housed in rack-mounted chassis'; stompbox pedals; in computer software; or built into an amplifier (e.g. a guitar amp), mixer, or instrument (e.g. a Hammond organ).

encore (Fr)

Again (i.e. perform the relevant passage or an entire song or tune once more)

engineer

In a live sound context, this refers to the audio engineer who controls the soundboard and/or leads the crew of audio technicians; in a recording context, this refers to the audio engineer who sets up and runs the technical aspects of a recording session.

The resonance loop created when a microphone or guitar pickup is placed close to a highly amplified speaker, often creating a howling or screeching sound. In most cases, musicians and sound engineers seek to avoid feedback with microphones and acoustic instruments; with electric guitar, especially in heavy metal and shred guitar playing it may be done on purpose.

fiddle

A slang term for a violin in bluegrass, country music, and folk music.

A jazz or rock term which instructs performers to improvise a scalar passage or riff to "fill in" the brief time between lyrical phrases, the lines of melody, or between two sections

flat

A symbol (?) that lowers the pitch of a note by a semitone. The term may also be used to describe a situation where a singer or musician is performing a note in which the intonation is an eighth or a quarter of a semitone too low.

foldback

In Britain, this is the term for an onstage monitor speaker that helps performers to hear their singing and playing.

football(s)

A colloquial term used (typically by U.S. session musicians) describing whole-notes, or a single whole note, which when printed within a musical score resembles the oblong shape of the ball used in the game of "American Football".

A continuous sliding from one pitch to another (a true glissando), or an incidental scale executed while moving from one melodic note to another (an effective glissando). See glissando for further information; and compare portamento in this list.

groupie

A somewhat pejorative term used to refer to fans of a rock group (typically refers to female fans).

A musical texture with one voice (or melody line) accompanied by chords; also used as an adjective (homophonic). Compare with polyphony, in which several voices or melody lines are performed at the same time.

head

The first (and last) chorus of a tune, in which the song or melody is stated without improvisation or with minimal improvisation.

A motif that is used in popular music to make a song appealing and to "catch the ear of the listener".

horn

In a jazz, blues, or R&B context, the term "horn" refers generically to any brass instrument (e.g. saxophone, trumpet, etc.). In a sound engineering context, "horn" refers to a flare-shaped housing into which a tweeter or loudspeaker is mounted as part of a speaker cabinet.

horn section

In a jazz, blues, or R&B context, this refers to a small group of brass players who accompany an ensemble by playing soft "pads" and punctuating the melodic line with "punches" (sudden interjections).

A jazz term used in 1950s and 1960s-era avant-garde and free jazz (e.g. Ornette Coleman) which instructs a soloist to improvise without following the chord changes being used by the rhythm section instruments.

A combination amplifier designed for keyboard players that contains a two, three, or four-channel mixer, a pre-amplifier for each channel, equalization controls, a power amplifier, a speaker, and a horn, all in a single cabinet. Small keyboard amplifiers designed for small band rehearsals have 50 to 75 watts, a 12 inch speaker, and a horn. Large keyboard amplifiers designed for large clubs or halls have 200 to 300 watts of power, a 15 inch speaker, and a horn.

A jazz term which is the equivalent of the classical term tacet; it instructs the player to cease playing for a section or tune.

lead (pronounced "leed")

In guitar playing, a single-note melody or solo line. In Britain, the term also refers to a patch cable which is used to connect an electric guitar to an amp.

lead bass

An expression applied (sometimes derisively) to a style of playing electric bass in which the player adopts a soloistic or melodic "voice", rather than, or in addition to playing the accompaniment role which is normally associated with the bass (e.g. Steve Harris of Iron Maiden).

leading note

The seventh note of a scale, which has a powerful "gravitational pull" towards the eighth note of the scale, which is the "home note" of the key. Because the seventh note of the scale has such a strong pull towards the eighth note, it is deemed to need to "resolve" to the eighth note.

Leslie

A brand name for a rotating speaker cabinet designed for use with the Hammond organ, but also used by some electric guitar players. The rotating horn and rotating baffle around the low-range speaker create an undulating effect.

line

A synonym for "melody" (as in the terms "melodic line"). (See also bassline).

line in

In an audio context, a "line in" is a jack found on mixers, guitar amplifiers, and recording devices. The "line in" jack allows a performer to add an input into a mixer, amplifier, or recording device.

line out

A "line out" jack provides an output signal from an amplifier or other device, which can then be patched into a mixing board, effect unit, PA system, etc.

An acronym for Musical Instrument Digital Interface, an industry-standard way for electronic devices to communicate information. MIDI connections can be used to connect synthesizers, electronic drum machines, sequencers, and so on.

The process near the end of the recording process in which all of the tracks of recorded music (e.g. 12, 24, or even 48 tracks of recorded vocals, guitars, keyboards, etc.) are blended and placed onto the Left and Right channels of a standard stereo recording. A "remix" occurs when the same initial tracks are given a new "mixdown", thus blending the tracks in a different way, adding different effects, etc.

monitor

In a live music context, refers to speaker cabinets which are used to amplify the singing and playing of onstage performers so that the performers can hear themselves' in a recording context, refers to studio reference monitors, which are heavy-duty, low-coloration speakers designed for playing back mixes.

monitor mix

In live audio, the monitor mix is the blend of vocal and instrumental channels which is amplified and sent through onstage speakers which are directed towards the performers. The "monitor mix" often differs a great deal from the "Front of House" mix. In a typical bar band, the "monitor mix" will consist mainly of vocals, with the possible addition of other instruments that need additional onstage monitoring volume (e.g. harmonica, saxophone, synth).

A symbol (?) that cancels the effect of a sharp or a flat (see in this list)

neck

On a guitar (e.g. acoustic guitar, electric guitar, electric bass), violin-family instrument (e.g. violin, upright bass) or other stringed instrument, the neck is the long, thin piece of wood which extends from the soundbox or body of the instrument and upon which the strings are put under tension between the bridge (on a guitar family instrument) or the tailpiece (on a violin-family instrument) and the headstock (for guitars) or the tuning pegs (violin) or machine heads (upright bass). The neck on acoustic and electric guitars and most electric basses has metal frets which divide the neck into semitones. Violin family instruments and fretless electric basses do not have frets.

noodling

A slang term of disapproval to describe superfluous meandering improvisation often inappropriate for a particular musical moment or performance.

It defines wandering within an ensemble format without clear musical force or context, hence the derivation from noodle or "wet noodle". A "noodler" would be any musician who contributes improvised musical figures not necessarily out of key or obviously sounding bad, but instead simply weak, incessant, and lacking any clear musical forethought, purpose or direction. The term is less applicable or fair in the context of improvisational genres reliant on sonics, discovery and experimentation.

notch filter

A very precise type of equalizer (e.g. a parametric equalizer) which can be used to boost or cut very narrow frequency ranges. Notch filters are used to lessen feedback with microphones or lessen overly resonant notes on acoustic guitars.

note-for-note solo

A live or recorded performance by an instrumentalist which reproduces a previously recorded improvised solo. In some cases, the recreation of the previously recorded solo may be faithful down to the smallest nuances, such as the use of "whammy bar" embellishments and "ghost notes".

Interval between one musical pitch and another with half or double its frequency. Octaves can be played one note after the other (e.g. a low C and then a high C), or they can be played together at the same time on instruments such as the guitar, piano, organ, etc.

octave pedal

An effects unit which electronically adds a note an octave (or two octaves) below or, less commonly, an octave above the note being played by the performer.

An abbreviation for the Fender Precision bass, a widely used model of electric bass manufactured by Fender guitars since the mid-1950's

pad

In reference to the music played by a keyboardist, this refers to a "sythesizer pad", which is a sustained background synthesizer sound used to accompany a band or singer; in reference to sound engineering, this refers to an attenuation circuit which reduces the gain of an excessively "hot" signal, typically by 20 dB.

In piano scores, this instructs the player to use press damper pedal to sustain the note or chord being played. The player may be instructed to release the pedal with an asterisk marking (*). In organ scores, it tells a Hammond organist that a section is to be performed on the bass pedalboard with the feet.

In reference to an electric guitar or bass, this refers to the magnetic or piezoelectric device which transmits the vibrations of the string or the guitar body to an amplifier; in reference to a song or tune, a "pickup" or the "pickup notes" refers to one or several melodic notes which lead into a subsequent section (e.g. a band leader will tell the band to "start from the pickup into the bridge").

pickup group or pickup band

A musical ensemble brought together for a single performance or a few performances.

In punk, metal, jazz, and other styles, this is a pejorative term used to refer to musicians or music fans who are deemed to not truly understand the music and its history ("That guy in the grey shirt says he's a hardcore fan, but he doesn't even know Black Flag...what a poseur!").

power chord

A chord consisting of a note, a fifth above, and the octave. It is widely used in rock, metal, hardcore punk, and other genres, usually with overdrive or distortion.

voicing

The choice of, and order of notes in the playing of a chord, which creates a different sound.

Another way that players may "voice" the same type of chord differently is by adding tones. For example, if a lead sheet shows the chord C Maj 7, some guitarists might play "E,A,D", a voicing which is "open" (insofar as it consists of large intervals) and which contains two "colour" tones, namely the sixth ("A") and the ninth ("D") of the chord.

VU meter

An abbreviation for "Volume Unit" meter; a sound level metering approach which measures the average sound levels. Commonly used in LED and needle indicators on mixing boards, sound processors, and other electronic gear.

It often employs passing tones to the next chord change so as to create an effortless sense of "walking". The approach can drive the beat or "groove" and is particularly useful to create movement and interest through elementary or simple chord progressions. It is commonly employed in Swing, early Rock and Roll, Rockabilly, Ska etc.

A cable with three ends, whereby one plug is joined to two plugs. This allows a single signal output to be plugged into two devices. For example, an electric guitarist could plug a single guitar into two guitar amps to create an unusual tone colour. Y-cables are also used to plug inserts into mixing boards (e.g. a compressor or reverb unit).

An abbreviation for impedance, as seen in the terms "High-Z" (high impedance) and "Low-Z" (low impedance), which are used to describe speakers, microphones, cables, etc. Impedance, which is the electrical resistance of a device, is measured in Ohms.
